Definitions

  • the present invention relates to a supporting body for guiding or tensioning a circumferential traction mechanism of a traction mechanism drive, including a front side which has a longitudinal sliding surface for contact with the traction mechanism, a diametrically opposed rear side which has an elongated receiving groove for the form-fitting accommodation of a reinforcement panel, the receiving groove being formed by delimiting elements which protrude, at sides of the groove, from the rear side.
  • the field of use of the present invention extends to traction mechanism drives in which torque or kinetic energy is to be transmitted from a first shaft to a second shaft with the aid of a circumferential traction mechanism.
  • guide rails and tensioning rails are used in the known prior art, guide rails being fixedly connected all over to the bearing of the shafts, and tensioning rails being swivel-mounted on the bearing, a pressure means being provided which presses the tensioning rail dynamically against the traction mechanism for the purpose of holding the latter under tension.
  • a reinforcement panel is therefore provided, which is inserted, in parallel to the running direction of the traction mechanism, into an opening opposite the contact surface of the tensioning rail and traction mechanism.
  • This receiving groove should neither be too large, since the reinforcement panel may thus, for example, vibrate or fall out of the receiving groove, nor be too narrowly dimensioned, since the insertion of the reinforcement panel is then made more difficult or impossible.
  • a guide is presented in DE 103 01 428 B4, which includes a receiving groove for accommodating a reinforcement panel, multiple ribs running perpendicularly to the longitudinal direction of the receiving groove being arranged on the inside of the receiving groove, with the aid of which the inaccuracies or planned tolerances during the manufacture of the receiving groove or the reinforcement panel may be compensated for.
  • the disadvantage thereof is, in particular, the increased manufacturing complexity of this approach.
  • the present invention covers the technical teaching that at least two delimiting elements on one side of the receiving groove are separated in the longitudinal direction by a spacing in the form of a gap.
  • Another advantage is that, due to multiple gaps of this type, the delimiting elements on both sides of the receiving groove have a greater mechanical deformability in the lateral direction, due to which inaccuracies or planned manufacturing tolerances of the receiving groove or reinforcement plant may be compensated for.
  • the supporting body and reinforcement panel are preferably designed in such a way that they are suitable, in particular, as the guide rail or tensioning rail of a traction mechanism drive.
  • a guide rail typically includes two fastening elements for bolts or screw connections on the traction mechanism drive, for example, while a tensioning rail typically includes a receptacle for the swiveling support on, for example, a bolt on the traction mechanism drive, while the reinforcement panel used in the supporting body has a contact surface for a pressure means fastened to the traction mechanism drive, for example a pressure spring or a hydraulic pressure means.
  • the supporting body is advantageously manufactured as a single piece by injection molding, which simplifies the manufacturing process.
  • multiple delimiting elements are provided on both sides of the elongated receiving groove, which thus define the receiving groove in the manner of laterally arranged crenellations.
  • the advantage of this approach is that the dimensions and positions of the delimiting elements may be variably configured to increase, for example, the mechanical load capacity.
  • each gap between two delimiting elements on one side of the receiving groove is situated opposite a delimiting element on the other side. This results in a gap-free projection in a lateral projection of the delimiting elements on both sides, which increases the mechanical load capacity.
  • each delimiting element on one side is situated opposite a gap on the other side, which has the same dimensions as this delimiting element.
  • one or multiple, preferably all, delimiting elements are bent or tilted in the direction of the receiving groove, so that, in the vicinity of the rear side of the supporting body, they are situated a greater distance from each other than from the supporting body. This results in a width tolerance of the reinforcement panel or the receiving groove.
  • FIG. 1 shows a perspective view of the schematic representation of a supporting body according to the present invention.
  • FIG. 2 shows a sectional view of another exemplary embodiment of a supporting body according to the present invention.
  • an elongated supporting body 1 has a rear side 2 , on which delimiting elements 3 are alternatingly arranged.
  • alternating means that one gap 4 is situated longitudinally between each of two delimiting elements 3 , the one delimiting element 3 on the other side being opposite elongated receiving groove 5 formed by delimiting elements 3 .
  • a receiving element 6 which has a circular recess 7 for accommodating a bolt of a traction mechanism drive 100 , illustrated schematically, for the purpose of the swiveling support of the supporting body, is also arranged on rear side 2 .
  • delimiting elements 3 form receiving groove 5 for accommodating a reinforcement panel 110 illustrated schematically and pressured by a pressure means 120 , also schematically illustrated.
  • Delimiting elements 3 are arranged in such a way that one delimiting element 3 , except for first delimiting element 8 and last delimiting element 9 in the longitudinal direction, is always situated precisely congruently opposite one gap 4 between two delimiting elements 3 arranged on the other side of receiving groove 5 . Due to a construction of this type, material and weight are saved without essentially influencing the mechanical load capacity, since the latter arises primarily due to the reinforcement panel, which is not illustrated.
  • FIG. 2 The cross section of another supporting body 1 according to the present invention is apparent in FIG. 2 , in which delimiting elements 3 are arranged in a not strictly alternating manner.
  • the cross-sectional plane intersects elongated supporting body 1 perpendicularly at a point at which delimiting elements 3 are present on both sides of receiving groove 5 .
  • delimiting elements 3 are positioned at an angle 13 of less than 90° on rear side 2 opposite front side 12 , whereby receiving groove 5 narrows as the distance from rear side 2 increases.
  • a reinforcement panel which is not illustrated in FIG. 2 , may thus be accommodated here, the reinforcement panel having a thickness which is wider than distal end 10 of receiving groove 5 and narrower than proximal end 11 of receiving groove 5 .
